[Asia Economy Reporter Moon Chaeseok] LG Electronics announced on the 14th that it has succeeded in wireless data transmission and reception over a distance of 320 meters outdoors in the 6th generation mobile communication (6G) terahertz (THz) band. The company plans to continue innovating customer experience (CX) in the upcoming 6G era.

Recently, LG Electronics succeeded in transmitting communication signals up to 320 meters outdoors using the 6G terahertz band (155~175GHz) at the Fraunhofer Heinrich Hertz Institute in Berlin, Germany. Terahertz (THz) wireless transmission technology utilizes the terahertz frequency band between 0.1THz (100GHz) and 10THz to enable ultra-high-speed data transmission speeds of up to 1 terabit per second (1Tbps). It is considered a core technology that will meet the demands and expectations of 6G mobile communications.

This achievement came about one year after the success of 100-meter outdoor wireless transmission in August last year. At that time, LG Electronics and the Fraunhofer Institute jointly developed a power amplifier in the 6G terahertz band, raising the output signal to a world-class maximum of 15dBm.

This success is particularly significant considering that the cell range of base stations used in typical urban areas is about 250 meters. It marks a step closer to commercializing 6G terahertz communication not only indoors but also across outdoor urban areas.

Ultra-wideband frequencies like 6G terahertz have short signal reach and suffer significant power loss during antenna transmission and reception. Therefore, developing 'power amplifiers' to increase transmission power and 'receiver components' to improve received signal quality has been the biggest challenge.

For this demonstration, LG Electronics and the Fraunhofer Institute succeeded in newly developing world-class core transmission and reception components, including a 'multi-channel power amplifier' with a total output exceeding 20dBm and a 'low-noise receiver signal amplifier' that minimizes noise generation. They also increased the module's integration density to facilitate future commercialization.

On the 23rd, LG Electronics will hold the '6G Grand Summit' event at LG Science Park in Magok-dong, Seoul, jointly with the Korea Advanced Institute of Science and Technology (KAIST) and the Korea Research Institute of Standards and Science (KRISS), where they will present the achievements in terahertz technology development along with other 6G development results.

6G mobile communication is expected to begin standardization discussions around 2025 and be commercialized by 2029. It will support faster wireless transmission speeds, low latency, and high-reliability communication compared to 5G. It is regarded as a means to enable the Internet of Everything Intelligence (AIoE), where people, objects, and spaces are closely and organically connected, as well as ultra-realistic media such as mobile holograms. For this reason, leading global companies are rushing to enter the field.

LG Electronics is strengthening cooperation with leading research institutes, universities, and companies both domestically and internationally. In addition to the Fraunhofer Institute in Germany, which participated in this demonstration, LG Electronics has established a 6G core technology R&D collaboration belt with KAIST, KRISS, and Keysight Technologies Inc., focusing on securing fundamental technologies.

In June last year, LG Electronics was selected as the chair company of the Next G Alliance, organized by the Alliance for Telecommunications Industry Solutions (ATIS) in the United States, and is expected to play a key role in future discussions on advanced 6G technologies and service directions.

Kim Byung-hoon, Vice President and Chief Technology Officer of LG Electronics, emphasized, "The success of the 320-meter outdoor demonstration has made the 6G technology goal of achieving 1 terabit per second transmission more realistic. We will continue to strengthen our 6G technology leadership through cooperation with research institutions and companies equipped with R&D capabilities."
